Description

[0001] Apparatus for marking with display [0002]

The present invention relates to a marking apparatus having a display, and more particularly, to a marking apparatus having a display on an upper side of a marking object and displaying an image of the marking object on a display, To a marking apparatus capable of providing a user experience that can input a pattern and capable of acquiring and displaying an image with less distortion.

Generally, a marking apparatus is a device for printing characters or figures on a workpiece. Since the marking apparatus can permanently print characters and figures, it is widely used in many industrial fields such as printing on various materials such as semiconductor chips, wood, .

In particular, when a user creates and inputs marking data, such as characters or figures, to be marked on an external input device such as a computer, the laser marking device deflects the laser beam in two dimensions by driving the laser scanner in accordance with the marking data, The on / off of the laser oscillator for outputting the laser beam in synchronization with the operation of the laser scanner is controlled to perform marking on the workpiece.

In order to control the irradiation position of the laser beam, a laser scanner for irradiating a laser beam has an X-axis servo motor (Y-axis servo motor) and a Y-axis servo motor A galvanometer consisting of a mirror (X-Axis Mirror) and a Y-axis mirror (Y-Axis Mirror) can be used. The laser scanner can control the irradiation position of the laser beam in the X axis direction or the Y axis direction by driving the X axis or Y axis mirror using the X axis or Y axis servo motor. However, when marking data such as characters or figures using a laser scanner, a deviation occurs due to mechanical characteristics (e.g., inertia of the X-axis or Y-axis mirror) of the laser scanner, Unlike the marking shape, there is a problem that minute distortion occurs.

Conventional laser marking apparatuses use various correction methods to prevent such marking errors. Typically, there are an optical correction method of adjusting the spacing of the X-axis or Y-axis mirror of the galvanometer, There is a physical correction method for performing position correction using a deviation between a position and a marking position that is actually marked. In particular, the physical correction method calculates the deviation between a marking position photographed while moving a marking position actually marked by a camera and a preset marking position. Since the camera repeatedly moves and stops according to the marking position actually marked, It takes a lot of time to measure the deviation of the marking position. In addition, there has been a problem that a measurement error of the camera itself occurs due to the continuous movement and stop of the camera.

Further, the conventional laser marking apparatus can only confirm the image to be marked by the user on the screen of the computer before the marking operation is performed, and expects the actual marking result of the workpiece according to the marking strength of the laser marking apparatus There was a difficult problem.

The touch display unit 140 may be fixed to the body of the marking apparatus through a hinge structure so that the user can open and close the marking apparatus. When an image of the object M to be marked is displayed on the touch display unit 140, a marking object (M) on the surface of the marking tray M may be located on the upper surface. Since the laser used when the marking unit 160 performs marking on the object M to be marked with laser light has a strong laser intensity when a laser for processing (for example, class 4 laser) is used, May cause damage to the user's eyes. In order to allow the user to see the marking object M by placing the marking object M in a transparent material such as a transparent display or glass, it is necessary to attach a film blocking the laser light or use a safety glass did. However, such a film has a problem in that it is expensive, and inconvenience occurs when a user wears safety glasses. On the other hand, when the marking object M is positioned at the lower end of the touch display unit 140 and the image of the object M to be marked is displayed on the touch display unit 140 as in the present invention, A user experience similar to the actual viewing of the object to be marked M to the user can be provided without causing it to occur.
